Temporal reliability of relative ET

Source: R/performance_indicators.R
wapor_calc_reliability.Rd

Population (default) or sample CV over time of AETI/ETc per pixel, or per zone through wapor_zonal_stats(). Monthly relative ET is the intended input; dekadal relative ET is noisy. No default class scheme (Molden and Gates 1990 bands are secondary and unverified for ET).

Usage

wapor_calc_reliability(
  ratio_stack,
  zones = NULL,
  id = NULL,
  sd_type = "population"
)

Source

Bastiaanssen and Bos (1999).

Arguments

ratio_stack

SpatRaster stack of AETI_t / ETc_t, or the output of wapor_relative_et_stack().

zones

Optional polygons for a zonal series.

id

Zone id column.

sd_type

"population" or "sample".

Value

A SpatRaster of CV (pixel mode) or a data frame (zone mode).
